Thanks all! I believe that art is a lifestyle.
Nope, just the cheap redi-mix stuff in 60# bags, 2bags per block and about 1ltr of an amendment (Silica 200mesh 60%, Feldspar 200mesh 25%, Lime 10%, and Titanium Dioxide 5% -basically old refuse glaze materials that I needed to dispose of).
Plastic forms were well oiled prior to pouring the mix.
